Preparation Steps

• Line a 9" x 9" baking dish with parchment, leaving an overhang on 2 opposite sides. In a large food processor, process Oreos until fine crumbs form. Transfer to a large bowl and add melted chocolate and salt. Stir until mixture resembles wet sand.
• Press half of Oreo mixture (about 1 ½ cups) into bottom of prepared dish; cover bowl and refrigerate remaining Oreo mixture. Top Oreo layer with ice cream, gently spreading to edges. Freeze until ice cream is firm, 1 to 2 hours.
• Gently press reserved Oreo mixture on top. Continue to freeze until set, at least 8 hours and up to overnight.
• Using parchment overhang, lift out bar and transfer to a cutting board. Cut into 9 squares.
